While starting a protobuf compiler I learned a little about autoconf. First it complains about version the protobuf code was using automake 1.10.1 and I had 1.7.9. so I upgraded to automake using “sudo apt-get install automake1.10″. Of course this upgraded my automake to 1.10.2 which still didn’t work.The solution was to run autoconf from the path/to/protobuf-2.1.0 but that didn’t work until I used “sudo apt-get libtool” to get the latest libtool. This uses the configure.ac and then generated Makefile.in from the Makefile.am.

Apple keyboard delete to right key remapping
Had some trouble getting the small aluminum keyboard to do a delete to the right. But with the help of this post I got it workings. Basically you need to create a .xmodmap file in your home directory with with the keycode of the key that you want to be Delete in this case 169 is for the “eject” button:
keycode 169 = Delete
Also by adding to .xmodmap:
keycode 133 = Alt_L MetaL
keycode 134 = Alt_R MelaR
You can map the command keys to Alt left and right respectively. You can use the “xev” program to determine the keycodes.

Viewing an old version of a file in git
Use “show” command, but you need to use the full path from the root of the git repo to the file, otherwise you’ll get an error such as below. This same error happens if there is any other error in the parameter, for instance a miss-spelling: Anyway, to look at a particular file use can use git log to see the various revisions: To see the current version you’d could use the the first entry. To see the previous version use the second sha1: I wonder if there is a simple syntax to get a particular revision such as:
$ git show HEAD:hxy
fatal: ambiguous argument ‘HEAD:hxy’: unknown revision or path not in the working tree.
Use ‘–’ to separate paths from revisions
$ git log –pretty=oneline -3 help.c
